Chinese character decomposition library for NLP and deep learning applications.
Decompose Chinese characters into basic structural components. Characters with similar structures yield similar decomposition results, making this useful as a glyph feature for deep learning models.
汉字拆字：将汉字拆解为基础部件。字形相似的字会得到相似的拆解结果，可用于深度学习模型的字形特征提取。
## Features | 特性
- Covers 20,000+ Chinese characters | 覆盖 20,000+ 汉字
- Zero third-party dependencies | 零第三方依赖
- Python 3.10+ support | 支持 Python 3.10+
## Installation | 安装
```bash
pip install hanzi_chaizi
```
## Usage | 使用
```python
from hanzi_chaizi import HanziChaizi
hc = HanziChaizi()
result = hc.query('名')
print(result)
```
Output | 输出:
```text
['夕', '口']
```
## Notes | 说明
Some characters (e.g. 农, 表, 衣, 囊) contain `\uf7ee` in their decomposition results. This is a Unicode Private Use Area character representing the bottom part of 衣 (the downward strokes), which has no standard Unicode codepoint.
部分汉字（如 农、表、衣、囊）的拆解结果中包含 `\uf7ee`。这是一个 Unicode 私有区域字符，用于表示"衣"的下半部分（撇捺结构），该部件在标准 Unicode 中没有独立编码。
Some characters cannot be decomposed. See [non_decomposable.txt](non_decomposable.txt) for the list.
部分汉字无法被拆解，详见 [non_decomposable.txt](non_decomposable.txt)。
